Abstract: (APS)
The singlet-Majoron model, with B−L broken spontaneously at the GeV scale, allows Ω=1 in νμ or ντ with masses in the range of 1 keV to 35 MeV. Neutrino-Majoron scattering leads to an unusual processing of the density perturbation spectrum; the resulting large-scale structure will be very similar to warm or cold dark matter. The Higgs boson may decay predominantly into invisible channels giving signatures with a missing-mass peak.
